我需要在屏幕上并行进行多个api调用。我注意到了一个奇怪的问题。当我收到一个api调用的套接字超时异常时，其他并行调用也得到相同的异常。如果我测试其他电话，它们工作正常。不知道确切的问题是什么。这是我的代码。

// getting ok http client
private static OkHttpClient getUnsafeOkHttpClient() {
        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

        // Remove cookies from the request
        CookieManager cookieManager = new CookieManager();
        cookieManager.setCookiePolicy(CookiePolicy.accEPT_ALL);
        cookieManager.getcookieStore().removeAll();

        try {
            final TrustManager[] trustAllCerts = new TrustManager[] {
                    new X509TrustManager() {
                        @Override
                        public void checkClientTrusted(java.security.cert.X509Certificate[] chain,String authType) {}

                        @Override
                        public void checkServerTrusted(java.security.cert.X509Certificate[] chain,String authType) {}

                        @Override
                        public java.security.cert.X509Certificate[] getacceptedIssuers() {
                            return new java.security.cert.X509Certificate[]{};
                        }
                    }
            };
            final SSLContext sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null,trustAllCerts,new java.security.SecureRandom());

            OkHttpClient client;
                client = new OkHttpClient.Builder()
                        .sslSocketFactory(sslContext.getsocketFactory())
                        .addInterceptor(interceptor)
                        .cookieJar(new JavaNetCookieJar(cookieManager))
                        .connectTimeout(REQUEST_TIMEOUT,TimeUnit.SECONDS) // set the request timeout
                        .readTimeout(REQUEST_TIMEOUT,TimeUnit.SECONDS)
                        .writeTimeout(REQUEST_TIMEOUT,TimeUnit.SECONDS)
                        .hostnameVerifier((hostname,session) -> true)
                        .build();

            client.dispatcher().setMaxRequestsPerHost(20);
            client.dispatcher().setMaxRequests(20);
            return client;
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

// making api call

public static void makeNetworkRequest(Call<JSONObject> requestCall,final Networklistener networklistener){

        // define the request callback object
        Callback<JSONObject> requestCallback = new Callback<JSONObject>() {
            @Override
            public void onResponse(Call<JSONObject> call,Response<JSONObject> response) {
                networklistener.onSuccess(response);
            }

            @Override
            public void onFailure(Call<JSONObject> call,Throwable t) {
                t.printStackTrace();
                networklistener.onFailure(CONN_FAILED);
            }
        };

        // make the request
        requestCall.enqueue(requestCallback);
    }

有人可以帮我吗？
